Introduction

This embedded TFT display is based on the Sitronix ST7735 chipset and is compatible with the SPI serial interface. This TFT display is 1.8 inches large, has 128x160 pixels and 262K colors (RGB666). For ease we are going to connect it to the FTDI FT232H device, of which there is a dedicated page on this site - refer to the above page for installation.

Python libraries

To manage this display, we can use one of the following Python libraries:

Library named "ST7735 Adafruit". this library requires the "Adafruit CircuitPython" library to be installed. In addition, the Adafruit ST7735 module must be installed using the instruction "pip3 install adafruit-circuitpython-st7735"
Library named "ST7735 FTDI". This library only requires the presence of the "PyFTDI" library and was built from Python library "Adafruit CircuitPython ST7735" on Internet.
